ABSTRACT:
A gasket structure for application to a hopper car door edge comprises an elongated flexible gasket of compressible material having a relatively thick body with a continuous tangentially projecting rib and a plurality of narrow elongated spring clips extending transversely of the gasket and each having a straight end portion underlying the gasket and riveted to the rib thereof, a straight intermediate portion angularly disposed with respect to the straight end portion, and an opposite end portion curved in the opposite direction with respect to the intermediate portion from the angulation of the straight end portion to form a nearly closed loop, the straight end portion being adapted to engage the inner surface of the hopper door web with the intermediate portion engaging the sloping peripheral rim of the hopper door and with the opposite end grippingly engaging the outer surface of the peripheral rim to secure the gasket against the door web.
